writing on cakes....fondant

I have a friend that wants a bible verse written on the side of a fondant covered cake. The problem is my handwritting is terrible. I always cut letters with cookie cutters and stick them on but this time that will be too large and wont work. i have the food safe writting pens and a letter stencil. Thinking i may try that. Kinda worried the black food safe writter black color will run. Any suggestions????

Print out the verse in the font/size that you want - tape it to bench - if you have a piece of glass use that - or use a piece of parchment paper over the top - you can pipe over your prtinted sheet with royal icing. Let it dry for a good 24 hours. You can then peel it off CAREFULLY and position on the cake
